The bodyis constructed of two parts, the intermediate portion (6 and the backplate (fl as indicated in the section Fig. 2, which is taken on the linea; m of Fig. 3. For convenience of construction the parts of the box maybe made from printers brass rules, which are supplied on the market inaccurate sizes. Thus to make the box A we may take a rule, say, sixpoints thick and machine it out, as shown in Fig. 7, presenting therecesses a? and a", and to the back of this we secure by dowelpins (4the back (0 which is a plain flat rule of, say, three points thickness.The coverplate a may likewise be made from a plain flat rule of, say,three points thickness having openings a to register with the dowelpins(1 and an opening ((7 to receive a screw (5, adapted to extend into athreaded hole a. in the intermediate body. hen such box is together, itis with the dimensions given twelve points in thickness and is adaptedto justify at once with any point system of furniture.

The hook is designated B. It is formed, preferably, as shown in Fig. 5,having its upper edge inclined or overhanging, as at 7), and havingbelow one or more projections or legs inclined on their upper surfaces.There are preferably two of these projections, 7) and 7), as shown inFig. 5. In use these projections enter the recesses a (f in the box, andthen when the hook is shoved toward the left of the box in Fig. 7 theinclined upper surfaces of the legs I) and engage with the inclinedlower surfaces o and a", carried by the box. Therefore the hook is drawnsnugly down into place. In its lowermost position the base of the legs7) and b engage the base of the recesses a and a", as appears in Fig. 3.

To hold the hook within the body, we provide a suitable lock, which ispreferably a wedge, as shown in Figs. 3 and 6. This wedge (designated C)occupies a portion of the recess a and bears against the adjacent edgeof the hook B, whereby as the wedge is forced downward into the box thehook is forced along the box and locked thereto. Notches 7) and 0 in thehook and wedge, respectively, allow their convenient removal by anysuitable tool.

Owing to the cooperating inclines in the box and the book, there isconsiderable leeway in the vertical position of the hook, de pendentupon the amount of overlapping of the cooperating inclines, which isvaried by the lateral positions which the hook may occupy. The wedge isinserted to a position which takes up the lateral space which the hookleaves between its end and the proximate end of the box-recess. Therecess (0 is preferably extended downward at the extreme end to give thewedge leeway. The wedge may thus clamp the hook tightly and the hookclamp the plate tightly, though the hook does not reach its extremesetting position, and thus the plate does not have to justify perfectlyon its base.

In use the plate N is laid upon the sectional base, (indicated by P,)with a stationary hook Q at two of its adjacent sides. On the oppositesides our hooks are employed, and the whole is locked in place by theusual furniture, wedges, &c. If it is desired to underlay the plate,(which can only be discovered after the form is on the press,) thewedges C and the hook ID are simply withdrawn. This allows the removalof the plate N without disturbing the rest of the form. Another platemay be substituted for the plate N with equal facility and withoutinterfering with the registration in any manner.

It will be seen that our clamping device takes up very little room, (asheretofore stated, it may very conveniently only require twelve pointsof space,) allowing the setting of other plates or type as close to theplate as desired. If it is desired to employ plates adjacent to eachother with a very narrow margin between them, the same hook may be usedto hold the adjacent edges of the two plates. The point of the hookwould then be made double, as indicated at I) in Fig. 8.

We claim 1. A printers plate-hook comprising a narrow vertical box, ahook portion consisting of a vertical plate adapted to enter a recess insaid box and having an overhanging upper edge, the hook and box havingcooperating inclines, the incline of the hook being adapted to takebeneath the incline of the box, and means for holding the hook withinthe box, substantially as described.

2. In a printers plate-hook, in combination, a box having a verticallongitudinal recess extending downward and then under an inclinedprojection, with a hook adapted to occupy such recess and having acorrelatively inclined projection, and means for forcing the hooklongitudinally within the box and thereby locking the plate,substantially as described.

3. In aprinters plate-hook, in combination, a body adapted to be lockedin a printers form and having a recess opening upward, a hook adapted tooccupy such recess, and means for locking the hook within such recess bymoving it longitudinally within the body, and a vertical wedge adaptedto occupy the recess in said body left vacant by said longitudinalmovement, substantially as described.

4. In a printers plate-hook, in combination, a narrow body having alongitudinal recess therein, a removable cover secured to the side ofsaid body, said body being adapted to be locked in a printers form, anda hook snugly occupying the recess in said body and being retainedtherein by said cover, substantially as described.

5. A printers plate-hook comprising a box,

a hook, and a lock therefor, the box consisting of an intermediaterecessed plate, and a pair of flat plates on opposite sides thereofthehook consisting'of a plate-adapted to snugly occupy the recess betweensaid fiat plates, and the lock consisting of a wedge, also adapted tooccupy such recess and force the hook longitudinally, the hook andintermediate platehavinginterlockingprojections, substantially asdescribed.

6. A body adapted to be locked in a print ers form, and having avertical recess which divides into two recesses a and (0* which haveoverhanging inclined surfaces a and 0 combined with a hook B adapted toenter said recess, and having legs 6' b with inclined upper edgesadaptedto engage the surfaces o a, substantially as described.

7. In a printers plate-hook, in combination, a body having a recess, ahook adapted to lie therein, said hook and body having inclinedcooperating faces whereby said hook may be drawn downward by beingforced internally within said recess, and means for so forcing saidhook, substantially as described.

8. The combination of a box built up of brass plates on the pointsystem, and a movable hook consisting of a plate having an overhangingedge adapted to occupy a vertical recess within said box and snuglyengage the inner side of the extreme brass plates, substantially asdescribed.

9. A printers plate-hook comprising a long narrow body adapted to belocked in a printers form with the length of said body parallel withtheplate and a hook adapted to be slid longitudinally within said body, thelongitudinal movement of said hook operating to draw said hook downwardand thereby lock the plate in the form, substantially as described.

10. In a printers plate-hook, in combination, a narrow body portionadapted to be locked in a printers form and a movable hook occupyingsaid body portion and extending parallel with the length thereof, saidhook having overhanging edges extended in opposite direction,substantially as described.
